How can women win in a marriage?

Especially when a woman is pregnant or just had a child, the man cheats. Because he got bored and has ”needs”. It happens to so many women and they’re always the one to take the blame. Im so sick of it.
How am i, a young girl, supposted to look forward to this knowing there's a high chance my husband will just cheat on me because of his needs and i can't do anything about it.
And no, its not easy to just ”pick better” so many men who are good people and fathers still do this and show no sign of any red flags.

You men need to do better.
